Purinergic P2X2 Receptors

A purinergic P2X neurotransmitter receptor involved in sensory signaling of TASTE PERCEPTION, chemoreception, visceral distension and NEUROPATHIC PAIN. The receptor comprises three P2X2 subunits. The P2X2 subunits also have been found associated with P2X3 RECEPTOR subunits in a heterotrimeric receptor variant.
